FLUE-STOP.

Specification of Letters Patent.

Application led February 14, 1906. Serial No. 301,056.

i flue-stops.

The object of the present invention is to improve the construction of flue-stops and to provide a simple, inexpensive, and efficient device designed for closing stovepipeholes, flues, and the like and adapted to present a smooth flat exterior surface when applied to a stovepipe-hole, so that it may be covered with wall-paper without causing .that portion of the wall tol present a different appearance from the other portions of the same.

A further object ofthe invention is to provide a flue-stop of this character having means for checkingl the heat and adapted to prevent the wall-paper from being either soiled or burned.

Another object `of the invention is to provide a flue-stop which will not allow either smoke or soot to enter a room and which when removed from af'stovepipehole will effectually prevent any soot or ashes from falling u on the floor.

A furt er object of the invention is to provide a flue-stop having means for firmly holding itself in position in a stovepipe-hole, so that it cannot be jarred or shaken out of its position or displaced by the Wind blowing down the chimney.

Furthermore, it is the object of the invention to provide a iiue-stop which may be compactly arranged for shipment and which may be easily put together by the purchaser or consumer.

With these and other objects in view the invention consists in the construction andnovel combination and arrangement of parts' hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood-that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacriiicing any of the advantages of the invention.

In the drawings, Figure l is a perspective view of a flue-stop constructed in accordance with this invention. Fig. 2 is a vertical sectional view showing the flue-stop applied to a stovepipe-hole. Fig. 3 is a rear elevation of the flue-stop.k Fig. 4 is a horizontal sectional view on the line 4 4 of Fio. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designates an inner circular head consisting of a disk of sheet metal and having its periphery bent inwardly at right angles to form aprojecting rim 2, and to provide a comparatively broad bearing-surface for iitting against the interior of a stovepipe-hole or llue 8. The rim also serves to stiffen the inner head, which operates to check any heat which may be passing up the chimney or flue with which the stovepipe-opening coinmunicates;

The inner stop or head 1 is spaced from an outer stop or cap-plate 4 to provide an intervening air-space 5, which also y assists in checking the heat, and it prevents the outer stop or cap-plate from becoming hot enough to burn the wall-paper. The outer stop or cap-plate, which is of greater diameter than the stovepipe-hole, is constructed of suitable sheet metal, and it presents Va smooth outer face and is adapted to be papered without causingl that portion of the wall to look different from the other portions of the same. The outer stop or cap-plate may be finished in any desired manner to cause it to present a more or less ornamental appearance, especially when it is not designed to be covered by wall-paper. The inner and outer stops are spaced apart by means of a narrow vertical strip 6 of resilient sheet metal, preferably steel, and it extends through a slot 7 of the inner stop, near the top thereof, and is provided with a curved extension 8, forming a clamping-arm which extends outward beyond the periphery of the inner stop before the device is applied to the stovepipe-hole, as clearly illustrated in Fig. 3 of the drawings, and which is adapted to be compressed to introduce it into the said stove-hole, whereby after the flue-stop is placed in position it will firmly clamp the stove-hole at the top thereof and assist in holding the device in position. The vertical stop or portion. 6 extends practically from the top to the bot- IOO tom of the inner stop and is secured to the said inner stop and to the outer stop or head by means of a centrally-arranged bolt 9 and an eccentrically-arranged bolt 10. The bolts 9 and 10 are provided with nuts,l as shown, and while other fastening devices may be employed for securing the parts together bolts are preferable, as they will enable the parts of the flue-stop to be easily separated and assembled. By this construction the device may be compactly arranged for shipping or storing and readily put together for use when desired.

The curved clamping-arm 8 cooperates with a combined clamp and scoop 11, constructed of spring-steel or other suitable material and consisting of an intermediate fixed bottom portion 12 and resilient side portions 13. The combined scoop and clamp, which is curved throughout its length, forms a partial flange around the flue-stop, and the in# termediate bottom portion 12 1s provided at its inner edge with a plurality of integral tongues 14, located at the terminals of the intermediate portion and at the center thereof and rigidly connectingthe saidl intermediate portion 12 with the inner stop or head. The inner edge of the intermediate portion is fitted against the inner faceofthe rim 2 at the bottom'portion of the inner stop or head, and the tongues14 are passed through' slots 15 of the said stop or head 1 and are bent at right angles, being located within the interveningvspace between the inner andl outer' heads, as clearly shown in Fig. 2vof the drawings.- By the arrangement ofthe tongues at the ends and central portions of the inner attached edge of the part 12'of the combined clamp and scoop the said part'12 is rigidly secured to the inner stop or head. The reysilientclampingportions 13 project beyond the periphery of the inner stop when they are not compressed within a stovepipe-opening,

, and they are adapted to engage the interior of a stovepipe opening at opposite sides thereof, whereby the flue-stop will be securely held in position and will be effectually prevented fro being j arred or shaken loose o'r displaced by the wind blowing down the chimney. In order to enable the resilient side portions 13 of the combined clamp and scoop to move freely across therim of the innerstop, they are recessed or cut away at their inner edges, the recesses 16 eXtending from the terminals of the fixed intermediate portion 12 to the outer ends of the side portions 13.

The combined clamp and scoop is adapted toy collect ashes and soot deposited in the stovepipe-opening adjacent to the device, and when the latter is removed from the stovepipe-opening the combined `clamp and scoop will hold such accumulation and prevent the same from falling upon the floor.

When the bolts are removed, the combined" clamp and scoop and the curved clampingarm may be iiattened out for arranging the device compactly for shipping or storing.

While two bolts are shown in the drawings, one of them may be omitted, if desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A Hue-stop comprising inner and outer stops or heads, the inner sto or head fitting within and conforming to t e configuration of a stovepipe-opening or iiue and the outer stop being of greater diameter than the same,
